Advent of Code JavaScript Template

This repository is a minimal template for Advent of Code, intended for JavaScript solutions.

Prerequisites

Install Node.js: https://nodejs.org/en/
Choose a code editor
- If you're not sure, use VSCode: https://code.visualstudio.com/
Choose a terminal emulator
- If you're not sure, you can use the one built into VSCode: https://code.visualstudio.com/docs/terminal/basics

Daily setup

For each day, perform the following steps:

Create a new directory for that day
Copy main.js into that directory
Create a text file called input.txt in that same directory, and paste the example input into it.

And that's it!

Writing your solution

Each main.js file includes code to load the inputs into a variable called inputs. This variable is an array, where each entry is one line of input. Each entry will start as a string, so remember to parse the input first if you want to use it as a number.

Write your solution below the comment saying "// put solution below this line".

You can print the solution using console.log.

Testing your solution:

To test your solution:

Open a terminal in the current day's directory
Run node main.js

To test with different inputs, update the input.txt file.

Once you think you have the solution, replace the example input with the real puzzle input (available at the bottom of the puzzle description), and run your solution again to get the answer.
